In the drawings, 1 indicates a chuck which may be of any desired construction. The chuck preferably comprises a frame l having adjustable arms l which are movable outwardly to engage the inner circumference of a core or forming member, indicated as an entirety at 2, to support the latter on the chuck. The chuck 1 may form part of a tire making machine and it may be rotated in either direction and at any desired speed by suitable mechanism, so that the tire carcass may be suitably formed on the core and then finished. In practice, it is customary to manufacture the tire carcass on the core while it is supported by a chuck and to then remove the core with the carcass thereon from the chuck and re-position iton a chuck while it is mounted on a finishing stand and to then finish the tire on the latter support.

Following this practice, I have shown at 3, in Fig. 2, an arm which forms part of a suitable finishing stand, this arm having a shaft 4, which rotatively supports a chuck 5. It is obvious that the chuck 5 may be driven by a suitable mechanism, if desired. The chuck 5 comprises a plurality of arms 6 each of which supports an adjustable member 7, the outer ends of which detachably engage the core 2 to support it. In carrying out one object of the invention, one of the arms 7 of the chuck 5 carries an interlocking member 8, preferably provided with bifurcations 8 which are adapted to be disposed on opposite sides of the neck 2 of the core and laterally extended so as to engage the inner sides of a pair of lugs 9 disposed upon and extending from the opposite sides of the neck 2. The bifurcations 8 and lugs 9 constitute interlocking means between the chuck 5 and core 2, and serve to secure one end section of the core to the chuck while the remaining sections are being moved to effect the collapsing operation and stripping or removal of the finished the from the core.

The core 2 consists of a plurality of sections each comprising a body portion corresponding in cross section to the shape of the casing to be made on the core and a neck portion 2 extending inwardly from the inner edge of the core section. The core may be divided into as many sections as desired, but by preference it is divided into an even number of sections, six being shown in the drawings, the end sections being designated 2, 2 and the intermediate sections being desig nated 2, 2, 2 and 2. Each section preferably abuts the adjacent section on radial lines except the abuttin ends of the two end sections 2 2, where the collapsing operation commences to strip a casing or tire from the core or the assembly of the sections is completed prior to the mounting of the core on the chuck 1. To permit these operations the abutting ends of the end sections 2 2 are curved about the axis upon which one section (2 and the adjacent section 2 swing one relative to the other.

11 indicates hinged connections between the core sections, the pivots for the connections being disposed at an angle to the axis of the core, so that each section swings relative to the adjacent section in a plane at an angle thereto or to the plane of the core, when all the sections are in assembled relation, the purpose of such arrangement being to effect movement of the core sections inwardly and laterally or out of the plane of the core or the plane of the casing, or finished tire supported thereby, to facilitate the stripping of the casing or tire from the core.

The construction of my sectional forming member permits me to effect the stripping operation (1) by holding one end section sta tionary and bodily swinging the tire casing and remaining sections relative to said end section and then repeating this operation, in progressive order, relative to each succeeding section or by revolving the end section about an axis adjacent its neck 2. the effect of which will be to progressively revolve each section, causing it to swing inwardly and the remaining outwardly disposed sections to move laterally. In carrying out the first mentioned method, the end section 2 is held stationary (see Figs. 12 and 13) while the casing and remaining sections are moved about'the hinge connections between the sections 2", 2. to strip the casing from the section 2 so that in fact the casing (as well as the remaining sections in the first stripping step of my process) is moved in the angular plane relativeto the section 2 until the section 2 is in a plane substantially parallel to the section 2", looking in a direction that is substantially parallel to the aXis ofthe casing. In the second step of my process, the

section 2 remains stationary (see Figs. 1a and 15) while the casing and remaining sections swingin a plane at an angle to the'section 2 about the hinged connections 11 between it and the section 2 until the-latter section assumes a substantially parallel relation to the. sections 2", 2. These operations are continued until-all the sections from the supported end section 2 to the free end section 2 are successively stripped from the casing, Figs. and (5 showing the final collapsed condition of the sections when the stripping operation has been completed.

The hinge connections '11 between each core section are provided for by bending the ends of the neck 2 laterally in opposite directions at an angle, as shown at 11*, 11', so that their side walls at each end will be spaced from and disposed parallel to the bent side walls of the neck-portions on the adjoining sections and interposing between the ends 11, 11 a plate, one end of the latter being preferably rigidly secured to the adjacent end 11 (preferably by cap screws 13) and the other endof the plate being pivotally connected to the adjacent bent end 11 by pivot pin 14', which may comprise a screw the inner end of which fits a screw threaded opening in the bent end 11. As will be understood, the plates 12 are rigidly secured and pivotally connected, respectively, to the corresponding ends of all the core sections, except the abutting ends of the neck portions 2 connectedto the end core sections 2?, 2", which have curved abutting ends, as already described. The neck portions of these two sections are detachably connected by a plate '15 rigidly secured to one neck. portion 2 and overlapping the joint between it and the other neck portion, being connected to the latter by the pin or bolt 15 extending through. openings formed in. the plate and the adjacent neck portion By preference there are two'plates 15 each disposed on one side of the adjoining neck portions 2.

16 indicates as an entirety interlocking means disposed between the abutting ends of the core sections and co-acting to prevent relative lateral movements therebetween when they are assembled in operative relationship. erably comprise a projecting.member on one end of each section and a correspondingly shaped recess formed on the opposite end of each section, so that when the sections are assembled tov form the'core, the projecting member on one end fits into therecess on the abutting end of the adjacent section and'thus preventsrelative lateral movements between them. The projecting members and recesses are preferably, elongated and extend in a radial direction relative to the axis of the core.

9. illustrates.v a core, the sections of which are formed from sheet metal, In

The interlocking means 16 prefsuch construction each section may comprise a ring 17 having a. neck portion 18 and a sheet metal section 19 shaped to form the body portion of-the core sections. hen the body portion is formed 'preferalny form it from two sections, as shown. The sheet metal sections may be secured along their inner edges to the ring 17 in any suitable manner, for example byweld ing; their outer edges maybe rolled or shaped to form a seam ofanydesired con struction, preferably in a manner which eliminates the formation of any rib on the outer surface of the core. The end walls of each section may be provided with caps 20,

suitably"securedtothe end edges of the sheet metal sections 19. In this form of construction, the caps 20 are shapedto provide the interlocking means 16, already described see Fig. .8.

When the core sections are cast of metal, I prefer to make the body portion and neck portion integral and also to make the-body portion hollow to insure lightness in the completed article, this construction being shown in Fig. 10. In such form of construction, the end walls of each section may be cast integrally. with the body portion and neck portion, or otherwisesecured thereto in'position. I t v Fig; 11 illustrates a core section having a neck portion 21 and a body portion 22 formed from wood. Where the body portionis formed in this manner it may comprise a plurality of sections, or the body portion may be formed from laminae.

In operation, the core sections are arranged in assembled relationship and positioned on the chuck 1. WVhile so supported, the casing isrmade on the core. If'the casing is to be stripped from the core, the latter may be provided with the interlocking means 8. But in ordinary practice, the core and casing are removed from the chuck 1 and positioned onthe chuck 5 of the finishing stand 3, at which time the bifurcations are interengaged' or interlocked with the lugs 9'. Next, the finishing operationsare carried outto complete the tire. To carry out this stripping or removal operation, the pin 15? is removed and. then the finished tire and core sections 2, 2, 2 2 and 2 are bodily moved about the hinge connection between the section 2 and section 2, the fcrmer section being held on the chuck 5 by the bifurcated member '8 until the adjacent section 2 occupies a position substantially parallel to the section 2 as this operation takesplace, due to the angular arrangement of the pivot between the sections 2 2, the tire and sections 2, 2, 2", 2 2 will swing in a plane on an angle to the section 2*, and

thus cause the tire to strip itself from the section- 2 Next, the finished tire and sect n 2 2 2 an 2*, are sw ngtabout the of sheet metal, I

pivot of the hinge connections between the section 2 and the next section 2 until the latter assumes a position approximately parallel to the section 2; as this operation takes place, the tire and sections 2, 2 2 and 2 swing in plane at an angle to the section 2 which causes the tire to strip itself from the latter section. Next, the finished tire and sections 2?, 2 and 2, are swung about the hinge connection between the sections 2 and 2 until the latter section assumes a position approximately parallel to the section 2; as this operation takes place, the tire and sections 2, 2 and 2 swing at an angle to the section 2, which cause the tire to strip itsc... from the latter section. Next, the finished tirw and sections 2 and 2, are swung about the hinge connection between. the sections 2 and 2 until the latter section assumes a position approximately parallel to the section 2 as this operation takes place, the tire and sections 2 and 2' swing at an angle to the section 2 and thus cause the tire to strip itself from the latter section. Next, the finished tire and section 2 are swung about the hinge connection between the sections 2 and 2, until the latter is substantially parallel to the section 2 as this operation takes place, the tire and section 2 swing at an angle to the section 2 and thus causes the tire to strip itself from the latter section. lVhen this last operation is com pleted, the finishedtire has been disengaged from all of the core sections except the last, viz, the end section 2. By pressing down wardly on the finished tire it may be readily disengaged or stripped from the end section 2. In stripping the tire from the core, as described, the chuck is preferably disposed in a vertical position so that the oper ator can manipulate the tire in the manner described.

After the removal of the tire from the core sections, the latter may be swung around in the reverse direction, which movement will cause them to assume their assembled relationship and thereafter the pin may be'replaced to hold the sections in position. The core may then be removed from the chuck 5 and repositioned on the chuck 1.

Waere it is desired to remove the tire carcass from the core before it is finished into a completed tire, such removal is elfccted in the same manner a above described.

in stripping the tire from the core, it will be noted that one end section of the series of core sections is supported on the chuck 5 or a stand to be later described) and then the tire and remaining sections are bodily swung about the hinge connection between such end section 2 and the next section 2; likewise in each succeeding operation the tire and remaining sections are similarly operated. I am thus enabled to attain relatively great leverage to effect such operations and as a result a tire of relatively large cross section, for example balloon or semi-balloon tires and other types of tires may be readily stripped.

In some instances it may be desired to remove the .core and the product thereon from the chuck 1 or chuck 5 to a stripping stand or supporting. device, such as shown in Figs. 1a to 16, inclusive. In these views, 28 indicates a standard having a suitable base 2%. At its upper end the standard carries a. bracket having a pair of bifurcations 8 with which the lugs 9 are engaged in the manner already described in connection with the chuck 26 indicates a rod supported its inner end by the bracket 25 and extending substantially horizontally. The purpose of the rod 26 is two fold-first, it serves as a support for the core sections as they are successively disengaged from the tire. For this purpose the rod is arranged to engage the section 2 at a point midway between the interlocking means 8 and the hinge connection between the section 2 and the section 2 (see Fig. 14:), so that as the stripping operations take place, each alternate core section (2", 2, 2 ,see Fig. 6) will engage with and be supported by the rod. Secondly, the rod 26 limits the swinging operation of each section relative to the previous section as the successive stripping operations are effected. The rod 26 may be removably supported in an opening 27 formed in the bracket 25. By preference, the bracket is extended in opposite directions relative to the standard 28 and provided at either end with bifurcations 8 and a rod 26 extends horizontally from either bracket so that the operation of stripping two tires can be carried on simultaneously, if desired. In the pref-erred form of construction, the openings 27 are aligned and a single rod extends therethrough and horizontally in opposite directions beyond the brackets 25.

It heretofore has been customary, in the use of collapsible cores either to use some form of chuck or other mechanical means to remove the core sections separately or collectively from the tire casings, or for the op :ator to strip the several sections by inserting his hands into the cavity of the easing and manually pulling each section therc from. In my improved core, one of the end sections is supported or held against rotation after which the core sections are removed by simply rotating the tire casing first about said end section and then the remaining sections successively. Thus the support for one end section serves to remove that section, then that section in turn, serves to hold the second section and toremove it from the casing, and so on until all the sections are removed and the casing stripped. This process or method of removing core from a tire casing is entirely new, so far as I am aware.

In Figs. 19 to 23 I have shown a stripping stand in which the construction is somewhat modified to enable the-stripping-operation and the re-assembly ofthecollapsed core sections to be effected by a rotatable member, which maybe operated by hand (as shown) or by power ,this form of mecha nism bein adapted to carry out the second method of operation-already referred to. In this form of construction, the end section 2 of'the core is revolved about an axis,orpreferably the axis of a support, while the easing is held stationary by the-operative or otherwise.

In these views, 28 is a base, which supportsa standard 29. At its upper end, the standard 29 carries a support 30 that is'provided with spaced lugs or Lip-standing walls 31 formed with aligned openings which form bearings for a shaft 32. 33 indicates an element fixed tothe shaft and serving as the means'by which the shaft may be driven,

described. The collar 34'may be fixed t'otheand prefer.-

shaft by a suitable set screw ably in engagement with the outer end of the adjacent bearing 31 so as to co-operate with the crank 33 (which is similarly arranged with respect to the'other bearing) toprevent endwise movement of the shaft In operation the core, with a casing mounted thereon'is placed on the support 32 with the lugs 9 thereof in engagement with the interlocking'rneans 35. Then,'while holding the casing stationary, the shaft 32 is rotated to revolvethe collar 34; such operation serving to (1) about the axis of'the shaft the end section about the hinge or pivot connections ll'between such section and the section 2. Due to the angular arrangement of the pivot connections 11, suchoperation will cause a lateral movement of the'casing and remaining sections and thus result in stripping the end section from the casing. As the rotation of the shaft 32 continues,

the end section willpick up the next section 2 and cause it to move in the manner already described with'respect' tothe section 2", and effect a stripping thereof from the Continued rotation will-effect a simthe spirit. and scope of the invention. disclosuresand description herein are purely illustrative and are not intended to .be in revolvethe end section 2 of'thecore' 32 and .(2) swing To re-assemble the core sections, the shaft 32 is rotated in the opposite direction. In this operation, the outermost end section first gravitates downw,ardly,-then the next sections follow in successive order (see Fi 21). As this unwinding or reverse rotation sections'in assembledvrelation until all the sections are assembled and the outer end section engaged with the inner *end sec- 1 tion.

'In the use of the term forming member in the appended claims I wish it to be understood as referring to various shapedjmeme bers without restricting my'im ention to a core forming member or supporting member that issubstantially round in cross section. Furthermore in the ,use of the term casing, I wishto be understood as referring to either a carcass or a finished tire, since the latter is similar to the-carcass except for the addition of the tire tread and other elements that are superimposed on the carcass. In the application of my invention, the separation or stripping operation of, the sectional forming member may'be effected after the carcass is ,made and priorto the finishing thereof, as well as after the tire has been completely finished ready for use.
